Powershell script fails to remove items on network share

HI,

Have a powershell script that would like to run on a shared folder to delete files older than 30days, however getting access denied on most of the folders and need to get rid of them but cant get the script to remove them even when changing the parameters to DELETE instead of Remove-Item

Help

Here is the script
